G70-G73: Diseases of myoneural junction and muscle

G72: Other myopathies

Other myopathies, classified under the code range G72 in the ICD-10 WHO 2016 classification, constitute a group of diseases that primarily affect the muscles in the body. Brought on by diverse causes such as genetic abnormalities, metabolic issues, electrolyte imbalances, or toxins, these conditions can lead to muscle weakness, fatigue, and at times muscle wasting. Indicative symptoms often include difficulty moving limbs, muscle cramps, and stiffness. Other myopathies are not generally transmissible from person to person as most of them are either hereditary or result from internal body conditions. Their progression can vary significantly, with some forms causing slow muscle deterioration over years, while others may lead to rapid onset of severe muscle weakness. These diseases impact the musculoskeletal system by impeding regular muscle function. It is essential to note that the severity and precise symptoms of these conditions can vary greatly from person to person.
